The fractal antennas have multiband behavior and also have the capabilities of the size reduction as compared to the other patch antennas. Ahybrid fractal boundary antenna has been designed and simulated in this paper for radio frequency energy harvesting (RFEH). The designed antenna has the multiband behavior, as it resonates at the two frequencies. The multiband behavior of the antenna helps in harvesting the energy from various frequencies band and improves the output of the circuit. This hybrid fractal boundary antenna uses the microstrip feed line to improve the matching performance of the antenna.

Radio Frequency harvesting has recently become one of the alternate approaches to power up low power wireless networks. This evolving technology opens the gate for positive energy renewal for wireless components. This paper presents a comprehensive review which includes all the important components in a RF energy harvesting system which are microstrip patch antennas, rectifier modules and power management modules. Different types of microstrip patch antennas and its designs and outputs are discussed. Rectifier modules with Schottky diodes operating under two different frequency bands are also compared and discussed. In addition, different methods of available power management circuits with different methods are also deliberated in this paper. This review also explores various key design issues and envisions some open research directions.

The aim of this work is, on one hand, to review the state of the art of the architectures and diodes used in radio-frequency energy harvesting systems, the idea here is to review the most recent works, as well as their characteristics, which include frequency, type of diode used, topology, maximum efficiency and corresponding power, and on the other hand to carry out simulations to determine the most appropriate case for any further work in the field. After having determined the most common topologies, we used the main known radio-frequency diodes to characterize them in a first step, clearly a process of comparing the results of the simulations of the different topologies is done by initially considering an identical frequency. and afterward determine the effect of frequency band on their conversion efficiency.

Abstract A circularly polarized ring cylindrical dielectric resonator antenna (ring-CDRA) of wideband impedance bandwidth is presented in this article. The proposed ring CDRA consist of an inverted rectangular (tilted rectangular) shaped aperture and inverted L-shaped slotted microstrip feed line. The tilted rectangular shaped aperture and inverted L-shaped microstrip feed line generate two-hybrid mode HEM11δ and HEM12δ while ring CDRA and slotted microstrip feed line are used for the enhancement of impedance bandwidth. The proposed ring CDRA is resonating between 6.08 and 12.2 GHz with 66.95% (6120 MHz) impedance bandwidth. The axial ratio (AR) bandwidth of 6.99% (780 MHz) is obtained between 10.76 and 11.54 GHz with a minimum AR value of 0.2 dB at a frequency of 11 GHz. The proposed geometry of ring CDRA has been validated with measurement performed by VNA and anechoic chamber. The operating range of the proposed radiator is useful for different applications in X-band.

A Multi Input Multi Output (MIMO) Rectangular Dielectric Resonator Antenna (RDRA) for 1.8 GHz Long Term Evolution (LTE) applications is investigated and presented. The antenna consisting of two rectangular dielectric resonator elements, both resonators are fed by microstrip feed line is etched on FR4 substrate. The simulated impedance bandwidth for port1 and port2 is 26.38% (1.6176-2.1093 GHz) and 26.80% (1.6146-2.1143GHz) respectively for |S11| ≤ -6dB, which can operate on LTE band 1-4,9,10,35-37 and 39. The gain of the MIMO RDRA is 3.2 dBi and 3.1 dBi at 1.8 GHz for port 1and port 2, respectively. The S-parameters, isolation, gain, and MIMO performance such as correlation coefficient and diversity gain of the presented RDR Antenna have been studied.

Radio Frequency Energy

The energy-harvesting radio frequency (RF) can be an attractive alternative energy capable of replacing all or some of the board batteries. The RF waves are present in several high frequencies ([Formula: see text] GHz) and at low power (a few [Formula: see text]W). An energy-harvesting circuit designed must provide 1[Formula: see text]V voltage at minimum that is able to operate an actuator or a sensor. The RF-DC rectifier is the main component of an energy-harvesting circuit. This paper presents a new design RF-DC rectifier circuit using the MOSFET transistors, the capacitors and the inductors. Our proposed circuit is a combination of an Inductor–Capacitor–Inductor–Capacitor (LCLC) serie-parallel resonant tank (SPRT) and rectifier cascade using the Dynamic threshold Voltage Cancellation (DVC) and the technique of the Internal threshold Voltage Cancellation (IVC). Our proposed circuit operates in dual frequencies [Formula: see text][Formula: see text]GHz and [Formula: see text][Formula: see text]GHz with a low input power [Formula: see text][Formula: see text][Formula: see text]W ([Formula: see text][Formula: see text]dbm) and [Formula: see text][Formula: see text][Formula: see text]W ([Formula: see text][Formula: see text]dbm), respectively. This circuit gives a Power Conversion Efficiency (PCE) of 56.9% and an output voltage [Formula: see text][Formula: see text]V for the frequency 2.543[Formula: see text]GHz and a PCE of 62.6% and an output voltage [Formula: see text][Formula: see text]V for the frequency 4[Formula: see text]GHz. The pre-layout simulations were performed using the Advanced Design System (ADS) and the technology used is CMOS 0.18[Formula: see text][Formula: see text]m from TSMC. The simulations were performed on the proposed circuit composed by three stages.
